Air Circuit Breakers

Introducing the M-PRO Plus protection relay

The M-PRO plus range of protection relay is the latestrange of advanced protection relay to compliment the M-Pact Plus air circuit breaker. The relay incorporates theunique features and benefits that have been proven withM-PRO but is an enhanced design for improved reliability,performance and application purposes.

The four types of protection units are M-PRO 17 plus, M-PRO 18 plus, M-PRO 30 and M-PRO 40 units.

Each M-PRO unit has specific features and benefitsdependant on the type of installation and applicationrequired by the user.This range provides inter-changeability essential whenupgrading circuits and providing limited down time foressential services.

M-PRO Plus has retained the innovative measurementcoils which due to their high accuracy and power ensureM-PRO Plus is self powered even when loads are very low.

The M-PRO17 Plus provides basic overcurrent and short-circuit protection with simple rotary switches for adjust-ment and clear indication of protection settings.Protection settings now available as low as 1.5 x Ir forimproved selectivity and co-ordination.'M-PRO17 Plus' has the additional option of Earth faultprotection.

Also introducing the new M-PRO18 Plus with the sameprotection functions as 'M-PRO17 Plus' but complete witha digital display.For ease of reference this unit also has a back light facilityproviding clear indication of the digital display.'M-PRO18 Plus' has the additional option of Earth faultprotection.

The M-PRO 30 and 40 units have a unique and innovativememory system enabling circuit protection settings andhistorical data to be stored remote from the associatedcircuit breaker.

Depending on the type of M-PRO Plus unit specified (see selection table) the following features are available:

- Adjustable protection curves- Auxiliary power inputs- Earth Fault Protection (unique combinations)- Neutral Protection (fixed or adjustable)- Ammeter (multi functions)- Thermal Memory- Historical Tripping data with real time - Reset Switch (manual and auto available)- LCD display (with timed backlit function)- Multiple adjustment and fault indication- Programmable inputs/outputs- Communication facility- Alarm contact- Mechanical Alarm Contact (optional)- Load monitoring- Making Contact Release (50kA)

M-PRO 17 Plus

M-PRO 18 Plus

M-PRO 30 - 40

Rated from 400 to 6300A the M-PACT Plus circuitbreaker has been designed to meet the most stringentdemands in fault detection and safe interruptionthereof.Available in 3 frame sizes:• Frame size 1 ranging from 400 to 2500A• Frame size 2 ranging from 800 to 4000A• Frame size 3 ranging from 5000 to 6300AThe range has been developed aesthetically andtechnically to co-ordinate with other protective deviceswithin our company for industrial/domesticapplications.All 3 frame sizes have unique look available with bothfixed pattern and drawout versions which can bemanually or electrically operated. These ACBs aredesigned to offer multiple mains connection options italso comes with a wide range of easy-to-installaccessories.

Specif ication

M-PACT Plus air circuit breakers comply with thefollowing specifications for low voltage switchgear:• IEC 947-1• IEC 947-2• IEC 947-3• VDE 0660 Part 101 and Part 107• Utilization category B

Approvals
